Kojima Productions’ is working away on Project Ogre, its still to be officially announced, FOX Engine-based, open-world game, but that doesn’t mean it won’t work on additional side projects at the same time – like it’s doing with Metal Gear Rising: Revengeance in cooperation with Platinum Games.

“I can’t really say too much about that project [Project Ogre] yet, but it’s a very subdued experience – it’s a little bit different to what I’ve done up until now,” Kojima Productions boss Hideo Kojima told Official PlayStation Magazine UK (via NeoGAF). “On the surface it will look similar, but once you get into it, it will be a different experience – and I’m hoping people look forward to that. But the Ogre project is going to take a lot of time, so I want to produce some other things on the side, like I’m doing with Rising. So while I’m working on Ogre there might be a couple of other projects going on at the same time.”

Kojima Productions worked in cooperation with Mercury Steam on 2010’s Castlevania: Lords of Shadow. Recently, Mercury Steam producer Dave Cox began teasing a sequel. Perhaps Lords of Shadow 2 is one of the projects Kojima is referring to.
